Filed: 2001-03-16
Abstract: PROBLEM TO BE SOLVED: To lower a high cut-off frequency without enlarging the resistance or the capacitance of a capacitor in a low-pass filter(LPF) in a semiconductor integrated circuit. SOLUTION: An input terminal 1, an MOS transistor 5, a resistor 2 and a capacitor 3 are serially connected and the other terminal of the capacitor 3 is grounded. The output terminal of an amplifier 6, with which a potential difference between both the terminals of the resistor 2 is defined as an input terminal, is connected with the gate of the MOS transistor 5.
